PREPARATION OF INTERNATIONAL SOLAR TERRESTRIAL ENERGY PROGRAM

日地能源方案项目自1991年开始作为日地物理学科学委员会国际合作研究项目。本研究的目的是建立项目的结构，并从国际和概念的角度对项目早期执行阶段的研究进行评估。这些项目涵盖了从太阳到地球大气层的日地关系领域的全部范围。通过行星际空间、磁层、电离层、中层大气、平流层和对流层区域的能量传输是主要研究的主题，主要集中在与太阳黑子活动相关的可变分量上;即，通过整个太阳-地球空间的紫外线能量和太阳风能的传输是关键目标。1991年至1993年，作为国家活动，每年举行STEP专题讨论会，讨论STEP在日本的详细研究结果和产品;结果已用日语出版，这些方案的摘要也已用英语出版。通过这项研究计划的活动，STEP国家计划的国际联系也已经建立。该计划的主要内容包括：建立STEP地区性地基、气球和火箭态势中心（GBRSC）;建立STEP仿真促进办公室（SIMPO）;协调地面观测设施与NASA、ESA、NASA、（4）建立了交换STEP数据的日本数据网（STEP Net），并建立了STEP数据分析的核心计算机站。

The project of the Solar Terrestrial Energy Program (STEP) has started since 1991 as SCOSTEP (Science Committee on Solar Terrestrial Physics) international colloboration studies. The present studies aim then to establish the structure of the projects and to evaluate the research in the early execution phase of the program both from the sides of the international and notional stand points of viewes.The projects cover the total range of the fields in the solar terrestrial relationship starting from the sun to the earth's atmosphere. The energy transport through the regions of the interplanetary space, magnetosphere, ionosphere, middle atmosphere, stratosphere, and troposphere is main subjects of the studies mainly being focussed on the variable components associated with the sun spot activities ; i.e. the transport of energy of ultra violet and the solar wind energy through the whole solar-terrestrical space are key objectives. As the national activities the STEP symposia have been held in each year from 1991 to 1993 to discuss the detailed findings and products of STEP in Japan ; the results has been published in Japanese, and abstracts of these programs have also been published in English. Through the activity of this study program, the international connection of the STEP national program has also been established. The main items excuted in this program arei) Establishment of the regional STEP ground based, ballom, and rocket born situation center (GBRSC).ii) The establishment of STEP simulation promotion office (SIMPO).iii) Coordination of ground based observation facilities with the satellite programs prepared by four space agencies such as NASA, ESA, Inter Cosmos and ISAS.iv) Establishment of the data network to exchange the STEP data in Japan, so called STEP Net, and also establishment of the core computer stations for the STEP data analysis.
